yup, its running. Is the raspberry pi connected to internet via wifi ? If so, change the config from `interface: eth0` to `interface: wlan0` , also change the address from `address: "localhost:8080"` to `address: "0.0.0.0:8080"` . And restart reef-pi service `sudo systemctl restart reef-pi.service` . You have to be root for all the things (sudo )

Yes. if the browser is from raspberry pi's display this will work (i.e. the touchscreen or some hdmi display attached to raspberry pi) , if not (i.e. if the brower is some other device, say mobile phone or tablet), then you have to change the conig to tell reef-pi to allow connecting from outside ,(address: "localhost:8080", change it to address: "0.0.0.0:8080", and restart reef pi using `sudo systemctl restart reef-pi.service`) , then you can connect to reef-pi UI from any device using the raspberry pi's ip. If that 10.0.0.47 (you can get it from the command `ip a s`), then your url will be `http://10.0.0.47:8080`

are you using the mcp3008 sensor board or pca9685 , or is it just the raspberry pi . If so, you have to disable the pwm, and sensor features, to do so set pwm and adc to false in /etc/reef-pi/config.yml and restart reef pi
```
enable_pwm: false
enable_adc: false
```
`sudo systemctl restart reef-pi.service`

You can only add component via the config file. In the beginning I had UI to add /remove components, but later I moved those to configuration file (/etc/reef-pi/config.yml) . How many relay , pwm device you want to configure?
